$3)$ Given the following recursive function: int getVal$($int x$,$ int y$)\{$ if $($x $==0)\{$ cout $<<$ y$+1<<$ endl; return y$+1$; $\}$ if $($y $==0)\{$ cout $<<$ "getVal $("<<$ x$-1<<",1)"<<$ endl; return getVal$($ x $-1,1)$; $\}$ cout $<<$ "getVal $("<<$ x$-1<<",$ getVal$("<<$ x $<<","<<$ y$-1<<"))"<<$ endl; return getVal$($ x $-1,$ getVal$($ x$,$ y $-1))$; $\}$ What is the output of getValue$(1,3)?$ Note that the output shows the trace $($i$.$e$.$ recursive function calls$).$
